BackForward Variable: Total lightning density

Definition
Full name Total lightning density
Definition Total number of detected flashes in the corresponding time interval and the space unit. The space unit (grid box) should be equal to the horizontal resolution and the accumulation time to the observing cycle
Measuring Units Dimensionless Uncertainty Units Dimensionless
Horizontal Res Units km Vertical Res Units N/A
Stability Units %/decade (Stability /decade)
